To
work with any of these samples, you will need the
following:.........................................Microsoft
.NET SDK
.........................................The objectspaces.msi package.
.........................................A copy of ORCA. The
installer (orca.msi) is installed with the
Platform SDK.

The installer (orca.msi) is installed with the
Platform SDK. Presumably you only need to install the Windows
Installer SDK.

Once you get
ORCA installed (it'll be in the Programs list without a containing group),
use ORCA to open objectspaces.msi and perform the
following three steps:

Click on the CustomAction table (on the left). The right-hand pane will show
6 entries, the topmost being SetRegasmPath. You should see that it thinks
RegAsm lives in the <FrameworkDir>\v1.0.3328 subdirectory. Change that to
v1.0.3705.

Click on the RegLocator table. The right-hand pane will show 5 entries, the
topmost being NETFramework. You should see that it's looking for version
information in SOFTWARE\Microsoft\.NETFramework\policy\v1.0 under the
3328 subkey. Change that 3328 to 3705.

Save objectspaces.msi.

You should now be able to install the ObjectSpaces
beta on VS.NET RTM.

What is ORCA?

ORCA is a Microsoft utility geared towards
modifying and validating windows installer packages. It is a database tool
created for setup Authors and Administrators that work with the windows
installer service. This utility is a part of the Windows Installer SDK
download along with other msi related tools.
You can use ORCA to open and modify msi packages and .ism project files.

The link to Windows Installer SDK should
be on the left hand side frame on the above site.

Click on that link to go to the next page
to download Windows installer SDK, which includes ORCA.

After downloading and installing Windows
Installer SDK, go to <drive>\Program Files\Microsoft SDK\Bin folder on the
machine to look for ORCA.msi.

Run ORCA.msi by double clicking on it,
which is the setup to install ORCA on your machine.

After installing ORCA on your machine, you
will be able to right click on any msi package and open it in ORCA. For
opening ism file, you may have to right click on the ism file and go to
"Open with" section to pick ORCA as the product to open with.
Note: Since ORCA allows for direct modification of the msi package or ism
file, which may have an impact on the project, It is recommended that users
make a backup copy of the msi package or ism file they are about to modify.
